Mainly the function is different.
Oil air compressor is the general use of electronic, printing, coating gas factory, oil-free air compressor is food, medicine, hospitals and so on.
Oil-free air compressor is cheaper, and oil-free air compressor is more expensive.
as long as the normal maintenance is quite durable
oil-free and durable.
1. materials are different:
1, oil air compressor: oil air compressor itself material containing oily substances, will pollute the terminal equipment.
2, oil-free air compressor: oil-free air compressor itself does not contain oily substances, to avoid the oil machine on the terminal equipment pollution.
2. gases are different:
1, oil air compressor: oil air compressor with oil lubrication, so the final discharge of the gas containing oil.
2. Oil-free air compressor: The oil-free air compressor is lubricated with resin material, so the final discharged gas does not contain oil.
gas circulation system
when the compressor is working, air is sucked in through the self-cleaning air filter, and the filter is automatically cleaned by PLC. The air enters the first-stage compression after being automatically adjusted by the inlet guide vane. The gas after the first-stage compression has a higher temperature and enters the intercooler for cooling (the water goes through the pipe, the air goes outside the pipe, and the water flow of the intercooler is required to be 110 m/h) and then enters the second-stage compression system.
In order to prevent the gas in the system from pouring into the compression cavity (avoid starting under pressure), a full-open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve into the exhaust muffler. Enter the primary aftercooler, the secondary aftercooler, and then enter the main exhaust pipe.
The air compressor flow rate is how much gas this machine can spit out per minute. You can understand it as the water output of the faucet, but it is not water, but compressed air.
The air filter (air filter) replacement cycle of an air compressor depends on a number of factors, including the environment in which the air compressor is used, air quality, running time, and the quality of the filter. Generally speaking, the replacement cycle of air filter is recommended to be every 2000 to 4000 hours or according
When looking for high-quality screw-type air compressors, many companies will ask: "Which is the best screw-type air compressor?" On this issue, Shanghai Grankering Group has become a highly respected product in the industry with its excellent water-lubricated screw air compressor products.
The water content of the product after treatment is a range value, usually between 2% and 10%, but the specific water content will vary due to various factors such as material conditions, working conditions and models. 1. Factors Affecting Water Content Material Situation: Different Raw Materials Treated with Water Content
Lubricating oil is usually not needed and should not be added to oil-free air compressors. The original intention of the oil-free air compressor is not to use lubricating oil during the compression process to avoid mixing oil into the compressed air, thereby ensuring the purity of the output air. The addition of lubricating oil may
The main difference between micro-oil screw compressors and oil-free screw compressors is whether they use lubricating oil during their work, and the resulting differences in performance and application. Use of lubricating oil: micro-oil screw compressor: this type of compressor
Oil-free air compressors are mainly used to provide pure and pollution-free air compression sources and are widely used in many industries. The following is a detailed summary of its main uses: Medical industry: Oil-free air compressors play an important role in the medical industry. It
When looking for an efficient, environmentally friendly, oil-free screw air compressor, Shanghai Granklin Group is undoubtedly a reliable choice. The water-lubricated screw air compressor produced by the group stands out in the market with its unique technical advantages and excellent performance. Water
Compressed air used in hospitals is an indispensable public medium in the medical system and is widely used in many clinical and auxiliary scenarios. Its core role is to provide power for medical equipment, maintain a sterile environment or directly participate in the treatment process. The following are specific uses and technical
